CARRIAGE-ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 389,583, datedSeptember 18, 188 8.

(No modeLl To all whom it may concern: Y

Beit known that I, GEORG-E L. LooMIs, a citizen of the United States,residing at Northampton, county of Hampshire, and State ofMassachusetts, have invented a new and useful CarriagevElevator, ofwhich the following is a specification.

My improvements relate to mechanism for hoisting vehicles and otherbulky objects upon the outside of buildings, so as to land them upon ordeliver them from an upper door with facility and safety, and with theadditional advantage of saving the large amount of space within abuilding required for a hatch or inclined way; and my invention consistsin the combination and construction, as hereinafter described, and moreparticularly pointed out in the claims.

' My invention is fully illustrated in the accompanying drawings, inwhich- Figure I is a plan view of a portion of the floor ofa building,having a part of the flooring broken away to expose the joists and therelative position of part of my mechanism therewith. Fig. II is asectional elevation of a building having my improvements combinedtherewith, and upon the dotted linexxof Fig. I. Fig. III is a partialsectional elevation of a building, showing my mechanism combinedtherewith in a different position from that shown in the precedingfigures and upon the dotted line y y of Fig. I. Fig. IV is an end viewof part of my mechanism, looking in ward; and Fig. Vis an end View ofthe same, looking outward and in section through the joists close to thewall of the building.

A is the front wall of a building.

B is a door-frame having its sill flush with the door C, and having in avertical line above it the beam D, for supporting the hoisting block d,and care the joists for supporting the ooring, all of these parts beingof the usual form of construction.

Eis a platform having a surface large enough to hold a carriage whenprojected beyond the front wall, A, and adapted to pass between thejambs of the door B. The platform E is se-V cured upon a frame, F,consisting of two beams extending from the outer end of the platforminward between the joists c, and having their cnds united beneath two ormore joists by a cross-piece, f. These beams, connected by the platformE and endf, rest upon frictioirrolls b, journaled in the joists cadjacent to the beams, and the beams bearing upon the rolls b can bemoved over the door-sill or in grooves cut therethrough to take withthem the platform secured thereto.

The inner end of frame F, for about the third of the length of saidframe, is covered by the flooring C, in near contact with the beams ofthe frame, so that when the platform E is extended and bearing theweight of a carriage, as shown in Fig, Il, the floor above the beams andthe joists above the cross-piece f secure the weighted frame F, bearingon the doorsill, or the friction-rolls nearest thereto, from tipping atits free end.

- As shown in Figs. Iand ll, the floor Gis cut away from immediatelyover the beams of frame F, from the door B inward, a distance equal toabout one third of the length of said frame, and the beams immediatelyunder the platform rise to lift said platform above the level of door C,so that the platform retracted, as seen in Fig. III, will pass over thedoor proper, and so that the platform when extended, as shown in Fig. I,will have behind it a surface over which things may be easily and safelymoved, the slight depression over the beams of the thickness of theflooring op posing no obstacle to the moving of vehicles over the beams.The shoulders e upon the frame F, coming against the floor at h, form astop to limit the retraction of the platform, and a lug, z', upon thejoists c, between the beams of frame F, forms a stop against which end fbrings up to limit the extension 'of the platform, so that the frame Fmay be run out or in without care being taken as to the eX- tent ofthe-movement given it.

Upon the floor C, and in a line centrally with the frame F, is awindlass-frame, G, having journaled therein two drums, H I. The lowerdrum, I, has wound around it several times, to secure sufficientfriction, an endless cord, J, as seen in Fig. I. The cord J, passingfrom drum I through an opening in the floor beneath, is carried over aroll, K, to obtain the proper direction, 'and from thence over a pulley,L,

IOO

fast beneath the sill of door B, having its upper lnember made fast tothe part f of frame F, as shown in the drawings, so thata rotation ofdrinn I by means of its crank-handle will slide the frame F as the drumis rotated inone or the other direction. From the drum H, provided withthe usual pawl and ratchet and crank-handle, passes the cord O to thehoisting-block d upon beam l).

In operation, the vehicle, being secured to the sling upon the end ofthe hoisting-cord O, is raised to the required height by the windlassand secured there by the pawl upon drum II to permit the operator toturn his attention to the drum l, which, by rotating, he causes toproject the platform beneath the suspended vchicle,whieh is then loweredto rest upon the platform, and can be from thence rolled into thebuilding or be carried therein upon the platform. The operation oflowering vehicles from the iloor to the ground is substantially thesame, and needs no particular description.

One operator can by this device raise any number of the heaviestvehicles, one at a time. Theinternal space hitherto required for a hatchor inclined way is saved, and it Inay be combined with buildingsfronting upon the narrowest streets.

NOW, having described my invention, what I claim isl. Thewithin-described elevator for carriages and other large objects,comprising` essentially,aplatform,E,adaptedtopass through the door-frameand project therefrom, supporting-beams extending from beneath theplatform between the joists c and supported upon anti-friction rolls,anda cross-piece, f, bearing upon the lower sides of the inclosed joistsand unitingr the inner ends of said beams,

a drum, I, mounted in a frame upon floor C in rear of the movable frame,and provided with an operating crank-handle, a continuous cord, J, woundupon said drum to pass therefrom beneath the floor over a pulley, L,located beneath the door-frame in fixed bearings and attachedintermediate the drum and pulley L to the movable frame, and ahoisting-cord, O, and pulley dfrom outside the wall A and over thedoor-frame B, all operating as and for the purpose set forth.

2. The within-described improved carriageelevator, consisting of amovable platform, E, arranged above the llooring 0f a building to form apart thereof and adapted to be projected therefrom through a door-frame,as B,'a frame for said platform, consisting of supportingbeams extendingfrom beneath the platform between the joistscand supported onfrictionrollers having a cross-piece, as f, against Athe lower sides ofthe joists, having offsets from the beams projecting through slots inthe flooring and forming supports for the platform E, to raise it abovethe flooring when retracted, and provided with stops and joists andflooring for limiting the movement of the platform in both directions, awindlass-frame, as G, drum I, continuous cord J, fast to frame F andpassing from roll I over pulley L and operating, as described, to imparta sliding movement to frame F upon the rotation of drum l, and drum H,cord O, and support l), outside of the building, substantially as shownand described.
